Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

OPA Policies Plugin

This plugin will fetch and display the OPA Policy an entity consumes! This is useful for displaying the OPA Policy for an entity in the Backstage catalog.

OPA Policy

Installation

You will need to install the backend plugin first into your packages/backend directory:

yarn add @parsifal-m/plugin-opa-backend

Then you will need to install the frontend plugin into your packages/app directory:

yarn add @parsifal-m/plugin-opa-policies

Configuration

You need to add the following annotation to the entity you want to display the OPA Policy for:

apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
  name: backstage-testing-grounds
  description: An example of a Backstage application.
  annotations:
    # Add the OPA Policy URL here
    open-policy-agent/policy: https://github.com/Parsifal-M/backstage-testing-grounds/blob/main/rbac.rego
spec:
  type: website
  owner: [email protected]
  lifecycle: experimental

You need to provide the full URL to the OPA Policy file as above in order for the plugin to fetch and display it.

Usage

You can then add it to your entity pages in packages/app/src/components/catalog/EntityPage.tsx:

import {
  OpaPolicyPage,
  isOpaPoliciesEnabled,
} from '@parsifal-m/plugin-opa-policies';

const websiteEntityPage = (
  <EntityLayout>
    <EntityLayout.Route path="/" title="Overview">
      {overviewContent}
    </EntityLayout.Route>
    // Other routes...
    <EntityLayout.Route
      if={isOpaPoliciesEnabled}
      path="/opa"
      title="Open Policy Agent"
    >
      <OpaPolicyPage />
    </EntityLayout.Route>
    <EntityLayout.Route path="/docs" title="Docs">
      {techdocsContent}
    </EntityLayout.Route>
  </EntityLayout>
);

Note that using isOpaPoliciesEnabled will then only display the OPA Policy tab if the entity has the annotation set.
